Wash potatoes in cold water and remove any sprouts. Pierce each potato about 8 times. I like to use the tip of a sharp knife rather than a fork.
Pat dry with a clean towel or cloth and rub lightly with olive oil.
Place on a lined baking sheet and sprinkle all sides with salt.
Bake at 425 for 30 minutes, then turn and bake an additional 25 - 40 minutes (depending on how many potatoes you have/their size). A medium potato will take about an hour.
When a toothpick, knife, or fork slides easily into the center of the potato, it is done.
